This is the bug for Provider Config changes related to JEP 246, subtask 8046943

Text describing the jdk.security.provider.preferred property added to the java.security file:
 
#
# A list of preferred providers for specific algorithms. These providers will
# be searched for matching algorithms before the list of registered providers.
# Entries containing errors (parsing, etc) will be ignored. Use the
# -Djava.security.debug=jca property to debug these errors.
#
# The property is a comma-separated list of serviceType.algorithm:provider
# entries. The serviceType (example: "MessageDigest") is optional, and if
# not specified, the algorithm applies to all service types that support it.
# The algorithm is the standard algorithm name or transformation.
# Transformations can be specified in their full standard name
# (ex: AES/CBC/PKCS5Padding), or as partial matches (ex: AES, AES/CBC).
# The provider is the name of the provider. Any provider that does not
# also appear in the registered list will be ignored.
#
# Example:
# jdk.security.provider.preferred=AES/GCM/NoPadding:SunJCE, MessageDigest.SHA-256:SUN
